The role of compressional dynamics in setting the scale-dependent rheology of granular flows: Application to the emergence of thin layer stability
Christopher Harper, Josef Dufek, Eric C. P. Breard
One great challenge of modeling granular systems lies in capturing the rheologic dependencies on scale. For example, there are marked differences between quasi-static, intermediate…
Electrified fallout from a wildfire plume
Joshua Méndez Harper, Josef Dufek, Larry Hartman
Large wildfires are becoming more frequent at temperate latitudes. Often, fires generate massive convective columns that can carry solid particles (ash) into the stratosphere. Like…
Basal force fluctuations and granular rheology: Linking macroscopic descriptions of granular flows to bed forces with implications for monitoring signals
P. J. Zrelak, Eric C. P. Breard, Josef Dufek
Granular flows are ubiquitous in nature with single flows traversing a wide range of dynamic conditions from initiation to deposition. Many of these flows are responsible for signi…
